My invention relates .tofa frictional re- I sistance element which is particularly adaptable for use in ,a hinge; v p

M Qne object of my [invention sthe provision ,ofa simple device for installation n a hinge pr similar tobjeet to createqthe des' ,ed frictional resistance between the fixed and movable parts thereof; I .Another object of the invention is to pro- ,Vyide .a frictional resistance element tWlllCh will prevent to a large degree undesired movementiof ,an open winclow. Another object of my invention is the provision ,of a frictional resistance element whichcannot be broken ,down 'by use, and which maintains a uniform valne at all times, because of automatic adjustment to compensate for .wear.

My invention possesses ether ob ectS and features of advantage, some offwhicb with the foregoing, will The set forth in the following description Qof the preferred form .of my inventiqn which is illnstratedt in' the dr wing e q mpa ed and i sing P Of the specification. It is to :be understood that I .do not lnyself to the showing made .by said drawings and description as may adopt variationsiofthe ,pnegferrtid form Within the vscope ,ofwmyginvention as set forth in thB ClalII iS.

Befeigring ;t0 the ,drawings:

Figure ,1 is a plan view {of encasement window hinge in which my frictional re- ,sistance eleinent,,has :been installed,

Eigure 2 is a plan view of my device, a

portion being broken away toshow ,thecom st ru ction.

Figure 3 is a crosssectionalview; plane of section being indicated by the line 2- t i In terms of broad inclusion my invention comprises a hinge embodying a friction ele ment of particular usefulness in mounting the casement type of window. The hinge comprises a slideway adapted to be fixed on the window sill, and on which is mounted a slide to which is pivotally attached a plate adapted to be fixed to the lower or upper edges of the window sash. Motion is imparted to the slide when the Window is moved, by means of a link which pivotally connects the sash and plate to the fixed slideway. Interposed between the slide and slideway are shoes resiliently engaging the slideway with a substantially constant pres sure.

,edgeof the plate 6 serves as .a?

acyhndrical roll, n V way 8 to move back and forth therein, is a of the cylindrical tglrical portion 8 of the is under More in detail my hinge comprises a mounting for a casement window and conk .s sts 1n alplate ,6 having suitable screw holes (to adapt it toflbe fixed to the em. One slideway the edge over in and is @fornied bw curling Mounted in this slideslide 9 having at each end ontheinneredge, rolled portions forming arms 11 of such size as to fiteasilv within the inner portion part of the slideway of the fixed ,plate 6. These arms are spaced apart anda-re; adapted to holdbetween them the frictional element ,of my invention.

The friction element consists of two shoes 12 of generally sen i cylindrical form, the

ends; 13 of which converge so that a conical. surface is provided at each end of each shoe. The two shoes are alike in shape and s ze and when placed togcther in the space between the arms 11 of the slide, provide a recess-within them, in which a coiled spring letnmay liewllhe parts are put together with an assembling jig which holds the spring under compression and when the jzig is removed the expansion of the coiled spring resses theends thereof into, theconical en s 13 of the shoes, thus tendingto separate the shoes and force them outwardlys against the inner surface of the cylinslideway. The spring compression between the conical ends of the shoes and is so designed that the desired frictional resistance is created by the .shoespwith the result that a resistance ofidefinite magnitude tends "to prevent .monement ,of the slide in the slide-way.

=Wear ,on the spring is prevented by the ,shoes lZ vehichsurround it and wliiclitend to exert an even pressure over the entire spring, so that there are no particular points of'contact which receive undue strain.

Pivoted to the slide 9 is a plate 16 provided with screw holes 17 for fixing it to the bottom or upper edges of the window sash, as the case may be, and pivotally conmeeting this plate to the slideway 6 is a link 18.

One of my hinges is mounted on the lower edge of the window and another on the upper edge, and when the window is moved resistance element interposed between the two plates is of such character thatwhile the window may be readily moved because of the leverage offered, it nevertheless t ends to remain in the position in which it is placed.

My hinge permits the window to be opened so that access may be had to both sides of the glass, and the window will stay where it is put against any tendency of the wind to move it.

While I have shown my invention embodied in a hinge it will be obvious without special illustration that myresist'ance element may be incorporated between any two elements or members between which it is desired to create a resiliently exerted frictional resistance.

I claim:

1. A casement window mounting comprising "a fixed split-cylindrical slideway, a slide arranged on said slideway, a plate pivoted to the slide, a link fixedly pivoted at one end to said slideway and at the other end to said plate, and cylindrical shoes for creating a frictional resistance between the slide and the slideway.

2. A casement window mounting comprising a fixed slideway, a slide arranged on said slideway, a plate pivoted to the slide, a link pivotally connecting said plate to said slideway. a pair of shoes mounted in said slide and having alined conical ends, and resilient means pressing into the conical ends for forcing the shoes into engagement with said slideway.

3. A casement window mounting compris-,

ing a fixed slideway, a slide arranged on said slideway, a plate pivoted to the slide, a link pivotally connecting said plate to said slideway, a pair of shoes mounted in said slide, and a coiled spring between said shoes for pressing the shoes into engagement with said slideway.

4. A hinge for a casement window comprising a fixed slideway, a slide mounted on said slideway and provided with a recess, a pair of hollow shoes in said recess and bearing on said slideway, a coiledspring interposed between the shoes for pressing them slide and the slideway.

6. In combination with a fixed slidewayand a slide arranged therein, a pair of holflow shoes mounted in the slide and having alined conical ends, and a coiled spring compressed between the ends and within .said

{shoes for creating a frictional resistance between the fixed and the movableparts of the hinge. 7. A frictional resistance element comprising a'slid'eway, a slide, a pair of hollow shoes, each of said shoes having alined conical ends, and resilient means bearing against said ends for pressing the shoes apart.

8. A frictional resistance element com;

prising a slideway, a slide, a pair of hollow shoes having alined conical ends, and a spring interposed between the' shoes and resiliently engaging against the conical ends to press the shoes apart.

9. A casement window mounting con prising a fixed slideway, a slide arranged on said slideway and having arms disposed at each end on the inner edge thereof, a

plate pivoted to the slide, alink pivotally connecting said plate to said slideway, and

means interposed between said arms for creating a frictional resistance between the 10. A casement window mounting comprising a fixed slidewa a slide. arranged on said slideway, a pate pivoted to the slide, a link pivotally connecting saidplate to said slideway, and a. coiled spring mechanically interposed between the slideand the slideway for creating a frictional resist- 1 ance therebetween.

In testimony whereof, I have hereunto set my hand.
